  • Insulated gate semiconductor device
    Patent number: 8779507
    Abstract: A gate lead wiring and an electrical conductor connecting the gate lead wiring to a protective diode are arranged in a straight line without bending along one and the same side of the chip. A first gate electrode layer extending on the gate lead wiring and the electrical conductor, which connects them to the protective diode, has one bent portion or no bent portion. Further, the protective diode is arranged adjacent to the electrical conductor or the gate lead wiring, and a portion of the protective diode is arranged in close proximity to a gate pad portion.
